Referring to the drawings, the ironing machine comprises a frame or housing'l which carries a roll 2, a shoe 3, and the driving mechanism for rotating the roll and for moving the roll toward and away from the shoe. The housing is provided with a flange l for supporting the ironing machine on the top of a suitable table 5.

The housing has a vertical hollow portion 6 which serves as the frame or outer casing for the electric motor used to drive the 'ironing machine. The `stationary member 'I of the electric motor is pressed into the hollow portion 6 and the rotary member 8 of the electric motor is supported on a shaft 9 the upper end of which is journaled in bearing I0 carried in a web I2 andthe lower end of which is journaled in a bearing I3 carried in a bearing housing Il threaded into the lower end of the hollow portion 6. The bearing housing I4 carries a thrust ball IIB which sup-V ports, the shaft 3. The web I2, which is integralV with the housing, forms a closure for the upper l0 perspective view of an ironing machine embodyend ofthe electric motor.

The motor shaft 9 projects above the bearing Iliand on its projecting end is out a worm I6 which meshes with a worm wheel Il. The worm wheel I l is rotatably supported on a shaft Il which rotates in a bearing I8 in a tube I9. The tube I9 is pressed into or otherwise nxed in a boss 20 in the sidewall of the housing I.l Integral with the worm wheel I1 is a pinion 2l which meshesvwith a gear 22 rotatably carried on a crank 23. When the gear 22 is in the position shown in Figs. 2 and 11, it meshes with a gear 24 fixed to a shaft 25 which -is journaled in boss 2B. The crankr23is integral with a shaft 21 which is rotatably carried in the sid walls of the ironer housing. The left end of the shaft 2l projects outside the housing (see Fig. 3) and dotted lines in Fig. 2, the shaft 2T is turned,- thereby moving the gear 22 away from the pinion 2l and breaking the driving connection between the continuously rotating pinion 2| and the gear 24. The shaft 25 is used to drive the roll in a manner which will be hereinafter described and the lever 30 therefore controls the driving connection to the roll. A thrust plate 30* is arranged between the housing and the adjacent faces of gears 2|, 22 and 24. It is provided with an enlarged opening 30b (Fig. 3) to permit movement of the crank 23.

'I'he construction of the roll 2 is shown in detail in Figs. 4 and 11. It comprises a sheet --metal cylinder 32 having a pad 33 on its outer surface. The pad 33 is held in place by a pad cover 34, the ends of which are secured to the inner periphery of the cylinder y32 by snap rings 35. On either side of a center line slightly to the right of the center of the roll are two disks 36 having outwardly projecting iianges 3l xed to the interior of the cylinder 32 and having inwardly extending flanges 38 which are xed to a bearing sleeve 39. The bearing sleeve 39 bears on a sleeve 40 which is rotatably supported by an eccentric 4I journaled on the left end of the tube I9. Endwise movement of the roll off the eccentric is prevented by a. retaining washer 4h mounted on a projection 4Ib on the eccentric. The eccentric 4I is xed to the shaft I8 so that the bearing between the eccentric 4I and the outside of the tube I9 also serves to support the left end of the shaft I8. Asl the shaft I8 is turned it is obvious that the roll will be moved laterally with respect to the tube I9. This lateral movement of the roll with respect to the tubey I9 is used to move the roll toward and away from the shoe and is also used to complete the driving connection to the roll by moving aninternal gear 42 which is carried by the roll into mesh with a pinion 43 fixedy to the shaft 25. The gear 42 and pinion 43 are arranged to be in mesh whenA the roll is pressed against the shoe and to be out of mesh when the roll is moved away from the shoe. Thus when the roll is 'pressed against the shoe it is rotated and feeds the material being ironed under the shoe. 42 and 43 mesh before full pressure is developed between the roll and the shoe so that the starting load on gear teeth is reduced.

As the gear 42 is moved into mesh with the pinion 43, there is a tendency for the teeth to jam. This tendency is increased by the fact that the gear 42 is an internal gear, with its teeth extending radially inward, and the pinion 43 is an external gear, with its teeth extending radially outward. It is, therefore, possible for a pairv of teeth on the pinion 43 to straddle a pair of teeth on the gear 42, in which case further approach of the gears would result in serious jamming. This tendency to jamming of the gear teeth is prevented by providing sufficient clearance between the bearing sleeves 39 and 40 so that the rollcan have a slight tilting movement. When the gear teeth strike, the pressure exerted on the teeth of gear 42 causes the roll to be tilted to move the teeth on the gear 42 away from the teeth on the pinion 43. During this tilting, the rotation of the pinion 43 causes its teeth to be moved to a position in which the teeth will not jam as theyI mesh. From one aspect the tiltable mounting of the roll can be regarded as a yielding mounting for the gear 42 so that as the gear is moved toward the pinion is can yield to prevent jamming of the gear teeth.

The eccentric 4I is provided with a pocket 4I which contains grease for lubricating the bearing' fed to the bearing surfaces through holes 4Id (see Fig. 4) in the sleeve 40 and in the eccentric.

The bearing sleeve 39 which rotatably supports the roll is located slightly to the right of the center of the roll as viewed in Fig. 4 so that when the roll is pressed against the shoe, the pressure exerted by the 'shoe on the roll tends to pivot the roll about. the bearing sleeve 39 in a counter-clockwise direction as viewed in Fig. -4 and therefore tends to hold the internal gear 42 in mesh with the pinion 43. In order to prevent jamming of the gear teeth due to too great a movement of the gear 42 toward the pinion 43, a collar 44 is fixed to the internal gear 42 which is adapted to engage a collar 45 on the shaft 25 and limit the movement of the gear 42 toward the pinion 43. The collars 44 and 45 are of the same diameter as the pitch lines of the gear teeth on therespective gears.

As described above the rotation of the shaft 25 is controlled by the lever 30 which moves the gear 22 away from the pinion 2l, breaking the driving connection to the shaft 25 on which the pinion 43 is fixed. By the manipulation of the The teeth on the Sears lever 30 it is therefore possible for the roll to remain stationary when pressed against the shoe. This is desirable when the ironing machine is used for pressing.

The roll is moved toward and away from the shoe by an arrangement for coupling the shaft I8 to the worm wheel I1 so that the shaft is rotated in steps of 180 degrees. The particular arrangement shown comprises an arm 46 pinned to the shaft I8 which is provided with radial slots in which are slidably carried clutch keys 41. The keys 41 are urged outwardly by springs 48 and the outward movement is limited by the anges 49 on a plate 50 fixed to the arm 46. When the keys are in the inner position shown in Fig. 3 there is no connection between the worm wheel vI1 and the shaft I8. When moved outward, the

- keys cooperate with notches 5I in a flange on the Worm wheel to complete' a driving connection from the worm wheel to the shaft I8. An odd number of notches are provided so that when one of the keys 41 4fits into one of the notches 5I the other key is held in its inner position by one of the teeth 52 between the notches. When the parts are in the .position shown in Fig. 2 the upper key 41 is held in its inner position by a lever 53 which is pivoted at 54 on the ange 61 of a bracket 55 fixed to the housing and which is pulled by a spring 56 against the key. A stop 53B limits the movement of the lever 53 by the spring. The lever 53 is provided with a ange 51 which engages the arm 46 and prevents movement of the arm in a counter-clockwise direction as viewed in Fig. 2. The lower key 41 is held in its inner position by engagement with a trip lever 58 which is carried on the upper end of rock shaft 59 journaled on the ironer housing. The linkage for operating the trip lever is shown in Fig. 11. It comprises a lever 60 pivoted at 6I on the under side of the table and urged by a spring 62 against a stop 63. The lever 60 is provided with a knee pad 64 sothat the lever can be operated by a sidewise 'motion of the operators knee. The lever 60 is connected by means of a linl"65 to a crank 66 fixed to the rock shaft 59. It is thus apparent that when the knee pad 64 is moved to the right (Fig. 11) the shaft 59 will be pivoted in a counter-clockwise direction kthereby moving the trip lever 58 away from the lower key 41 and permitting the spring 48 to force it outward into engagement with one of the notches 5I, thus completing a driving conl nection from the worm wheel I1 to the shaft I8.

This key will now be termed the driving key. As soon as this driving connection is completed the lever 60 may be released and it will be returned to its normal position by the spring 62. When the driving key is moved into one of the notches 5I, the other key 41 is held in its inner position by one of the teeth 52. This is due to the fact that the number of notches 5I is odd. The worm wheel rotates in a clockwise direction as viewed in Fig. 2. After the iirst few degrees of rotation of the shaft I 8, the upper key 41 is clear of the lever 53, and the lever is held against the stop 53a by the spring 56. As rotation of the shaft I 8 nears 180 degrees, the arm 46 strikes the lower edge of the iiange 51 on the lever53 and moves the lever 53 in a counterclockwise direction as viewed in Fig. 2. When the shaft I8 has rotated through degrees the driving key is moved out of the notch 5I by engagement with the ange 61 on the bracket 55, thus, breaking the driving connection to the shaft I8. At this time, the arm 46 is clear of the lower edge of the angeil, vand lever I3 is moved to the position shown in Fig. 2 in which the flange I1 f prevents counter-clockwise .movement of the shaft I8. The tendency to' counter-clockwise movement of the shaft I8 may be due to the breaking ofthe driving connection to the shaft before the eccentric reaches dead center as the roll is pressed against the shoe. or to the tendency been moved out of the notch 5IY by the flange 81.

The purpose of the lever 53 is to prevent the key remaining in a position so close tothe slots 5i that it continually clicks against the teeth 5,2. The lever 53 is therefore in the nature of a follow up device to increase the spacing of the driving key from the notches 8l. At this time, if the lever 88 has been released, the lever 58 will occupy a position in which it will hold the other key in its inner position. It isV thus apparent that for each actuation of the lever 80 the shaft I8 and the eccentric 4I connected thereto will be turned through 180 degrees. If the lever 68 is continuously held to the right, the shaft i8 will be rotated continuously, the driving connection vto the shaft being completed successively by each of the keys 41. i

The trip lever I8 has an upturned end 58* which serves as a stop to limit the movement of the arm 46 in a clockwise direction as viewed in Fig. 11. This tendency to clockwise movement of the arm 48 may come from overtravel of the shaft i8 due to inertia, from friction between the arm 48 and the worm gear '|1, or from the pressure exerted on the roll by the shoe if the eccentric is moved slightly past dead center when the roll ispressed against the shoe. The stop 58B is a precautionary device which is normally not brought into use.

It is desirable that the movement of the roll toward and away from the shoe be effected with- .slot 89 in a disk 10. The disk 10 is secured to the tube i9 by set screws as shown in Figs. 8 and 11. The radial slot 68 is located so that as the eccentric is rotated the roll is moved directly toward and away from the shoe without any substantial turning movement. As the roll moves toward the shoe, the tongue 88 slides in the slot 89. 'Ihe movement of the sleeve` 40 and the roll carried thereby can best be described as a pivotal movement about the tongue 88. During the first part of the movement the sleeve 40 is pivoted about tongue 68 in a counter-clockwise direction, as viewed in Fig. l1, until the eccentric has turned 90 degrees from the position shown. During the next 90 degrees of turning of the eccentric, the

wardly about tome I8 'during the first quarter of the movement of the eccentric and then swung downwardly about tongue 68 during the second` quarter of the movement of the eccentric into ensagement with the shoe.

, from the shoe, the roll is first swung downwardly about the tongue 48 during the flrst quarter of sleeve 48 is pivoted in a clockwise direction about the tongue 68. The roll has the same movement as .the sleeve 40 until it contacts the shoe at. which time such movement is prevented by the friction between the roll and the shoe and by the completion of the driving connection to the roll which starts the rotation of the roll. While( moving towards the shoe, the roll is swung upthe movement of the eccentric and then upwardly about the tongue 88 during the second quarter of the movement of the eccentric. During the movement of the roll toward the shoe, the roll appears to be first lifted and then moved downward into engagement with the shoe. During the movement of the roll away fromgthe shoe, the roll appears to be -first lowered and then raised. If the direction of rotation of the eccentric were reversed it is apparent that during the movement of the roll toward the shoe, the roll would first be lowered and then lifted into engagement with the shoe and that during the movement of the roll away from the shoe the roll would first be lifted and then lowered. It is obvious that by changing the shape of the slot 88- the movement of the roll may be varied.

The shoe 3 comprises an arcuate metal plate 1lil which is heated by suitable electric heating umts (not shown). 0n the upper surface of the plate 10* are secured a pair of studs 1i which extend through the web 12 of' a channel-shaped bracket 13. 'I'he bracket 13 is clamped to the plate 10* by sleeves 14 around the studs, and a cover plate 15 is clamped between the upper ends of the sleeves 14 and nuts 18 threaded on the studs. The flange 13 of the bracket 13 is provided with round holes (not shown) and the flange 13b of thebracket is provided with elongated slots 11 (see Fig. 10) through which extend arms 18. Endwise movement of the shoe on the arms 18 is prevented by pins 18S. A leaf spring 19, arranged on the stud 1i adjacent the flange 13h and between the under side ofthe arms 18 and the upper side of the web 12 biases the shoe downward so that the arms 18 normally restagainst the upper ends of the slots 11 and the shoe is held parallel to the roll. When the roll is pressed against the shoe the shoe pivots about the openings in the flange 13 until the pressure on the shoe is equalized. With this support it is obvious that the shoe can tilt in all directions about axes in the plane of and passing through the center of the shoe, thus equalizing the pressure at all parts of the shoe. Clearance holes 19n are provided in the shoe cover to permit tilting of the shoe. Another advantage of the shoe support is that the greater portion of the arms 18 isconcealed beneath the shoe cover 15. The armsV 18 are preferablyl chosen to have suillcient resilience so that they serve to limit the pressure between the roll and the shoe to a safe value to allow for variation in thickness of the padding and of the material being ironed.

The arms 18 are xed ina hinge member 88 carried on a pin in boss 82 on the upper end of the ironer housing. The hinge member is normally held in a i'lxed position by a pin 8| which is slidably carried in bosses 82 and 83 and is urged by a spring 84 into a recess 85 in the hinge member. Therpin 8l is provided with a knob 88 by means of which the pin can be pulled out of the recess 85. When this is done the shoe may be pivoted away from the roll. This movement permits the shoe to be cleaned and also serves to release the pressure between the roll and the shoe incase the power supply should fail while the roll was pressed against the shoe.

While moving away Operation In the use of the ironer the material to be ironed is arranged on the roll. The lever 68 is then moved to the right as viewed in Fig. 'l1 by pressure exerted on the knee pad 64, moving the trip lever 58 away from `the adjacent key 4l. The spring 48 moves the key 4l outward into one ofthe notches I inthe continuouslyr rotating worm Wheel Il thus completing a driving connection from the worm wheel Il to the shaft I8. This key will now be termed the driving key. The pressure on the knee pad 68 may now be released, and the trip lever 58 will be returned to its normal position' by the spring 62. 'I'he shaft- I8 rotates through 180 degrees at which time the driving key is pushed inward to disengage the driving connection by engagement with theange 61 on the bracket 55. Since the lever 58 has now been returned by the spring 62 tothe position shown in Fig.- 11, the other key lll is held in its inner position by the lever 58. shaft I8 through an angle of 1.80 Adegrees from the position shown in'Fig. 1l will turn the eccentric 4I through 180 degrees, thus pressing the roll against the shoe 'and completing a driving connection to the roll by moving the gear 82 into mesh with the pinion 43. When the ironing operation is completed the lever 68 is again pushed to the right and the shaft I8 is rotated through 180 degrees in the manner described above. At the end of this movement the roll is away from the shoe and the parts occupy the position shown in Fig. 11.

Ifthe ironer is to be used for pressing, the lever 38 is moved downward from the position shown in dotted lines in Fig. 2, moving the gear 22 out of mesh with the pinion 2l. This breaks the driving connection to the pinion 53 so that the roll is not rotated when the gear 52 is moved into mesh with the pinion 48.

In Fig. 13 is shown a slightly dierent construction for supporting the roll. In this construction the roll is supported on a tube 8l which is pressed into or otherwise xed in a boss 88 on the ironer housing. At each end of the roll are eccentrics 89 and 89a which are rotatably supported on the'tube. The eccentrics are connected by a tube 90 which is concentric with the tube 81. The eccentrics rotatablyV support the roll bearings 9| which are carried in sleeves 92 secured respectively to flanges 93 and 93a on rings 94 and 913a secured to the innersurface on the roll casing 32. Sufficient clearance is provided between the eccentrics and the bearings 9i so that the roll can have a tilting movement to prevent clashing of the driving gears for the roll. The roll is held on the eccentrics by a retaining washer 94b threaded on a stud 94 on the eccentricl 89. As in the previously described construction the eccentrics are yturned by the shaft I8 which extends through the tube 8l. 'I'he shaft I8 is secured to the eccentric 89. 'I'he driving connection to the roll is effected in the same manner as inthe previously described construction, by means of an internal gear 95 which is iixed to theyiiange 94"L and which is moved into and out of mesh with the continuously driven pinion 43 fixed on the shaft 25. These gears are so arranged that they are in mesh when the roll is pressed against the shoe and are out of mesh when the roll is moved away from the shoe. v

In Figures 12, 14 and 15 is shown another modlcation of the ironing machine. In this construction the housing 96 which contains the drivasas,

Rotation of the ing mechanism for the ironer is provided with an integral tubular projection 8l which projects within the roll. The driving mechanism contained within the housing is identical with that shown in Figures 2, 3, and 1l, the corresponding parts being indicated by the same reference characters. The roll is likewise of the same construction as that shown in the previously described ironer. At the center of the roll are 4secured rings 9S and 99- having, respectively, inwardly extending iianges H88 and IUI secured to a lsleeve |82 carrying a bearing 583. The bearing is rotatably supported on an eccentric IDB which is journaled on a hub I85 at the end of the tubular projection 9i. There is-sumcient clearance between the eccentric and the hub E85 so that the vroll can tilt and can also have a slight bodily movement relative to the hub. A spring-pressed friction pin HB5 carried by the eccentric bears on the hub m5 and holds the roll straight and' steady when away from'the shoe. The eccentric is connected to the shaft i8 by means of an arm lill having a pin H18 fitting in a hole in the eccentric. The arm lill is connected to the shaft I8 by means of avpin Ill@ fixed to the shaft which ts in notches M8 in the arm. The arm i811 is slid.

able on the shaft and is held in the position shown by a spring lli arranged between the end .of the arm and a washer M2 on'the shaft. The arm I8? is pinned to a tubular sleeve l i8 which is provided with a handle H43 adjacent the end of the roll. When the parts are in the position shown, the shaft i8 is connected to the eccentric E88. By pulling on the handle IM, the notches Il@ in the arm Iil'i may belmoved clear of the pin 89 in which case the eccentric may be turned by means of the handle IIE since the pin Hi8 will still fit in the hole in the eccentric. This construction provides an alternative means for turning the eccentric in case of a failure of the power supply which would prevent the turning of the shaft it by means of the motor drive.

The shaft I8 is rotated in successivev steps of 180 degrees by means of the driving mechanism shown in Figs. 2, 3, and 11. When the shaft is in the position shown, the roll is spaced from the shoe. When the shaft has been turned through 180 degrees froml this position the roll is moved by the eccentric against the shoe. This movement of the roll completes the driving connection to the roll by bringing an internal gear II5 tween the roll and the shoe.

carried by the ring 99 into mesh with a pinion IIS carried on the continuously driven shaft 25. 'I'he driving connection to the roll is, therefore, effected by the movement of the roll toward the shoe. When the roll is moved away from the shoe this driving connection is broken. The clearance between the eccentric |84 and the hub I permits a tilting and bodily movement of the roll relative to the hub |05 which tends to prevent clashing of the gears I I5 and II6 as they aie moved into mesh. That is. if the teeth of the internal gear II5 are in line with the teeth of the pinion I I6, the pressure exerted on the teeth of. the internal gear causes the internal gear to be moved away from the pinion. During this movement of the internal gear, the pinion, which is continuously rotating, turns to a position in which the teeth will not jam as they mesh. The tilting movement of the roll also helps alignthe roll with the shoe so that uniform pressure is obtained throughout the surface of contact be- 'Ihis tilting does not materially affect the mesh of the gears II5 and IIB since these gears are located close to an internal gear'carried by the roll adjacent the The shoe 3 is of the same construction as that A shoe in Fig. 4 and is supported in the same manner on a pair of rods and H'I'. The rods ||1 and ||1` extend through openings in the side walls ofthe housing I3. The rod H1* is shorter than the rod ||1 and its end tits in a recess ||3 `inaboss H8. 'Ihe rod ||1 ntsina recess |20 frame, a shaft carried by the frame having a driving pinion nxed thereto,- the position of said driving shaft being such that the driving pinion is in mesh with said vinternal gear when the roll is pressed against the shoe and is out of mesh in a boss |2I. -The rod ||1 is provided with an annular groove |22 into which extends a pin |23 carried by a leai' spring |24, The pin |23 prevents longitudinal movement of rod and thereby holds the rods Ill and II'I inl a fixed position relative to the housing 96. When the pin |23 is lifted clear oi the groove |22 the shoe may be moved endwise until the rod ||1 is clear of the housing 96. The shoe may then be pivoted about the rod ||1 which is still journaled in the housing. This maks possible the movement of lthe shoe to a position in which its work contacting surface may be easily cleaned. The complete removal of the shoe from the housing is prevented by means of a snap ring |25 which prevents the removal of the rod II1. From one aspect, the rods and H1* can be considered as providing a hinged mounting for the shoe.

'I'he above described clearance between the roll Vand eccentrica 4|, 89, 89", and |04 to provide a yieldable support for the internal gears 42, 95, and IIB and prevent jamming of the internal gears with the pinions 43 and H6 is the sole invention of the applicant Wardwell and is being claimed in his application Serial No. 134,850.
